' PILEIIDELIVEBY FOR PRIENTING Application filed September To all whom iii may concern.

Be it known that I, J OSEJPH C. WnLAen,

a citizen of the United States, residing at the city of Cincinnati, in the county of Hamilton and'State of Ohio, have invented certain new and useful Improvements in Pile Deliveries for Printing Presses, of

which the following is a specification.

My invention relates to a pile delivery means for printing presses and applies particularly to the pile or stack of circulars,

cards, papers, sheets, and the like, after they have been singly piled one on top of the other by the delivery fly of the press, and consists essentially inmeans for keep-, ing each sheet delivered by, thefly onto the pile, in alignment and keeping'the corners of the" deliveredsheets from turning over, especially at the corners thereof.

"It is a well known fact that on account quick operation of" the delivery flyand the parts of the printingpress adjacent thereto, and from drafts and air, the upper sheet or sheets of the pile having atendency to turnup, especially at the corners, thus interfering with the proper alignment of the pile of sheets,-and turning over 'ofthe corners, mar-ringthe sheet and thus causing great inconvenience and annoyance.

. the use of my attachment these objections areovercome, inasmuch as I provide guard fingers, which, when the delivery fly is receiving another sheet to place upon the top of the pile, are in touch with the last delivered sheet and hold it until the delivery fly ready to place another sheet upon the pile,,the guard lingers moving out of the way until said sheet is placed upon the pile and then again holding this sheet until another is ready to be delivered by the fly.

My attachment is simple, practical and efficient, cheap of manufacture and can readily be applied to the printing presses I and possesses a high degree of utility.

The various'features and advantages of my invention will readily become apparent from reading the following specification.

In. the accompanying drawing forming part of this specification:

Fig. 1, is a plan view of my invention,

Fig. 2, is a section taken" on line 2-2 of Fig. 1, and

Fig. 3, is Fig. 1.

In the drawing, 1, represents the rear jogger, andto the same I connect the brackets section taken on line 33 of a7, 1924. Serial no. 740,320.

2, and in these brackets I place the shaft 3 which carries the fastened thereto. 7

Securely fastened to the shaft 3, I provide an adjustment lever 5 which allows shaft 3 to return to a nedetermined point-.

Loosely mounted onshaft 3, i provide a V lever which carriesa' pawl 7 mounted on the screw stud 8. This pawl 7 engages with a one'tooth ratchet 9, which 18 also securely mounted to the shaft 3; a coil spring 10 guard fingers l securely which is mounted on the screw studS is for V the purpose of holding into engagement the pawl 7 into ratcheti). A coil spring 12 1s mounted on .the shaft 5 and has one end fastened to said shaftat point 113 and the; i

' other end is connected to one of thebrackets belt 17, which belt is fastened to a cam 18 which is mounted Ol'liit rock or cam shaft 19 of the printing press. A chain 20 has one end fastened to the spring 15 at" point 21 and the other end tothe pawl 7 at the point 22; A spring 23 mounted on the shaft 3 has one end fastened to one of the brackets 2 and the other end of same springis fastened to the stud screw 8 at the point 24;, which allows the lever 6 to return to its normal position as shown in Figs. 1 and 2, or when the guard fingers 4 are down'in touchwith the pile of paper. An adjusting screw 25 is mounted in plate 26, for the purpose of adjusting the return-travel of-the lever 6 and an adj usting screw 26 is for the purpose of adjusting the return travel of the fingers4 through the agency of the adjustment lever 5.

The guard fingers 4; on the shaft 3 are raised in position as shown in Fig 3, in

dotted lines, and out of the path of the sheet being delivered by the delivery fly, in the, following manner: As cam shaft 19 of the printing press rocks, thecam 18 draws for-" ward on belt/17 to the spring 15, to lever 6 causing said lever to travel in'said direc tion, the lever 6 carrying'pawl 7, which env is i this position the fingers are out of the path of the fly delivery) The .iipgers reinain in this position for a very short time and as the next sheet is placed on the pile by the fly delivery, then the pawl 7 is released from the ratchet 9 by reason of chainQQ being pulled to its limit of length, thus disengaging said pawl 7, which allows the spring 12 to act and return thelingers quickly to the position shown in Figs. 2 and 3, that is, down on the pileoit sheets.

The adjusting lever 5 onshat't 3 will;allow fingers 4 to return to theadjustcdposilion obtained. by the adjustingscrew Qtfrand as the rock or cam shaft 19 o l: the printing press returns to its previous position allows the lever 6 with itspawl '7 to return toorig inal position and again become engaged with the ratchet 9, which is also securely mounted to shaft 3. llhespringlO causes the pawl 7 tohear down and properlyengage in said ratchet 9, as thechainiZO becomes slack, which allowsthe pawl 7 teen gage with said ratchet.

1 I may use any number of guard lingers toundnecessary, and in the presentinstance I use four, the two outer guard fingers being used being wide sheets and. the two inner guard lingers areused for sheets which are not of great width, although preferably 1 use them all with wide sheets.

While I have described one specific and preferred method of carrying my invention into effect, it will be readily understood that I may make changes and modifications therein which will fall Within the scope of this specification and still fall within the scope of my invention.

What I claim as new and my invention and desire to secure by Letters Patent is 1;. In anattachment for printing presses of tlie cliaraeter described, in combination with the rear jogger and the cam or fly shaft of the said press and the piledel ivery mechanism, of a shaft supported on the rear jogger, guard fingers, attached to said shaft,

means for oscillating said. Shaft, said guard lingers moving w th sa d shaft as the same 13 oscillated, to bring said guard fingers down upon the pile as each sheet is delivered by the tly delivery mechanism, and raising saidlingersott of said pile at a predetermined time, to allow the fiy delivery mechanism to deliver the next sheet.

In an attachment for printing presses i an shaft, means for oscillating said shaft, said guar l,,fingers moving with. said shalt as the sa i neis o. llatethtobring said guard lingersdown upbn the pile, as each sheet is. deliyered by the. lly delivery mechanism, and raising said lingers oil' of said pile at edetermined time, to allow the fly demechanism, to del iyer the next sheet, means connected: with the oscillated ying the g! M rd ti: for adme in its oscillating movement.

in an attachment torprinting presses o't' the' characterdesc Ibed, in combination with the rear jogger and the cam or fly shaft of the said pressand the pile delivery in ehanism, of a sha'tt supported on the rear jogger, guardhngers, attached to said shalt, means tor oscillating said shaft, said guard fingers n'ioving with said shalit as the same is oscillated, to bring said guard fingers down upon the pile, as each sheet is delivered by the fly delivery mechanisnnand raising said lingers olt' of saidpile at a predetermined. time, to allow the fly delivery mechanism to deliver the next sheet, the raising and lowering ojlithe guard fingers regulated through a cam or fly shaft and intermediate mechanism hetweensaid cam and the shaft.

In testi noi'zy whereof, i aflix i'iy sig;'.. ture at Cincinnati Qhio, .this 18th day of September 192%.
